Application filed March 14, 1918. Serial No. 222,336.

To all whom t may concern.' y

Be it known that I, ALBERT KINGSBURY, a citizen of the United States of America, and a resident of Pittsburgh, Allegheny county, and State of Pennsylvania, have invented certain new and useful Improvements in Bearings, of which the following is a-speciication, reference being hadto the accompanying drawings, forming a part thereof.

My invention relates to bearings, particularly thrust bearings and combined guide and thrust bearings. It has special reference to thrust bearings of the type which employ tiltable bearing portions, segments or shoes and is suitable for use with inclined -or horizontal shafts, such for example as the propeller shaft of a ship.

v The problem of providing lubrication for horizontal or inclinedA thrust bearings of this class is usually more difficult than that of supplying oil to thrust bearings for vertical shafts, because in bearings of the horizontal or inclined type a considerable portion of the thrust engaging surfaces are, in many cases,

above the level of the oil chamber or reser' voir, while in bearings of the vertical type all portions of the engaging surfaces can be completely immersed in a bath or pool of lubricant.

One object of my present invention is to provide a simple and improved bearing structure which is particularly adapted for use with a horizontal or inclined shaft and which is arranged to automatically flood all of the bearing members with a copious supply of oil when the bearing is in operation.

Another object is to provide a combined guide and thrust bearing structure in which a continuous circulation of oil will be maintained over all of the thrust engaging surfaces and also from end to end of the guide bearings, and also one that will function as aforesaid irrespective of 'the direction of shaft rotation. 't

Another object is to provide a simple and effective oil scraper and distributor which is arranged to collect the oil from a revolving oil carrying surface on one of the bearing `members and which is preferably held loosely in place so that it is free to float on the revolving surface Ias the bearing member revolves.

Another object of my invention is to provide a thrust bearing composed of tiltable bearing portions, segments or shoes which are disposed in engagement with a portionA only of the thrust collar, and to also provide means for equalizing. or equitably distributing the bearing pressure between the bearing portions without depending on a complete circumferential distribution of the equalizer parts.

In order that my inventionmay be thoroughly understood, I will now proceed to describe the same in the followingspecification and will then point outthe novel fea.-

tures thereof in appended claims.

The invention is capable of receiving a variety of mechanical expressions, some of which are-shown on the accompanying drawings, but it is to be expressly understood that the drawings are for the purpose of illustrationonly and are not to be construed asa definition of the limits of the invention, appended claims reference 'being had -to the forv that purpose.

p Referring to the drawings:

Figure 1 is a longitudinal section of a detail perscraper resting and floating on its rotating collar support and provided in the respective figures with vertically and horizontally adjustable gates. j

The gates are shown in detail in Figs. 8 and 9.

F ig.,10 is a partial section, corresponding to a portion of Fig. l, of another structure which also constitutes an embodiment of my invention.

In the form shown 10 is a bearing housing having oil reservoirs 11 near each end at the bottom and a cylindrical chamber which forms an inner housing 12 forthe thrust members and a support `for the bearing segoil reservoirs are shown i one side of the central vertical plane of the of parts ments o r shoes which form guide bearings 13 and 14 are provided one on each side of the chamber 12.

, 15 designates a horizontal shaft which is rotatively mounted in the guide bearings 13 and 14. Afiixed to the shaft is a thrust collar 16-which lits loosely into .the cylindrical chamber 12 of the housing. A

The housing may be divided, either in a horizontal plane or in an oblique plane as shown in Fig. 2. The oblique plane is paruse in 'a restricted space, as in a ship. The as formed only at bearing, see Fig. 2, but this a'rrangement'is also intended to adapt the housing to the space where it is to be located. i The upper half of the housing is designated 18 and has a cover 19 suitably fastened in position as by bolts 20; .The arrangement is such that either-the cover 19 may be removed to inspect the bearing or. the upper half ofv the housing may be removed. 'The cover however ma bel removed without draining the oil from t e housing. n

When the thrust pressure sustained by the bearing is not sufiiciently high to make a large number of shoes necessary, a group of shoes 21 may be disposed in the lower part of the housing only and engage only the lower part of the thrust collar 16. In the form cross-section and into the'r'ing sector 23 are terposed betweenthe -l first two 26 resting onone shown in Fig. 3, there are three'shoes in an arcuate series although .some other number may be used if desired. The shoes are preferably supported on equalizing or pressure- ,distributing means of any suitable construction, preferably comprising an arcuate series of equalizing plates 22.

In the form shown, the shoes 21 and the plates 22 are held in place and supported by a ring sector 23 :which is channel-shaped in which the equalizing the respective ends of stepped blocks orend members 24 which coperate with the end equalizing plates and (with the end shoes of the group.l l

Each equalizing plate has ablunt knife edge' 25 .extending radially across one surface, theradialledges of the opposite surface bein recessed to form ledges 26. Alav ternate'b ocks are reversed so) that the ledges coperate to form loose, halvedor overla ing joints. Thus, -in the form show n 1n ig. 3, two of the lates 22 are mounted on thesupporting surace of the rin sector 23 in the bottom of the channel. ne'of the plates is, reversed and rests on the ledges 26 of the first two. The other two are inend blocks 24f-and the plates mentioned, one of the ledges ofthe steps of the end plates 22'are set. At

block in each case..

' of said openings pivotal mount is provided for each shoe 21 by three of the plates and the coperation of the plates is such as to equalize the pressure sustained by the shoes without necessitating a complete circumferential series of said plates.

Eachshoe may be provided with a hardened 'insert 27 having a spherically curved surface arranged to coperate with the blunt knife edge of the corresponding equalizing plate, and similarly hardened inserts may be ticularly suitable for a housingdesigned for v sired.

In the form shown in Fig. 1 the cylindrical housing l2 is provided with an oil passage 28 at the bottom whichestablishes communication between the inner' chamberand the reservoirs 11. Near the outer ends of the guide bearings 13 and 14 are stufiing boxes 30 and 31 and adjacent to the stuiing boxes are annular grooves 32 and 33. Each of the Stuffing boxes is shown ras comprising an adjustable wedging ring 34 which is secured to the *end of the housing by bolts 35 and squeezes a suitable packing material' '36 against the beveled edge surface 3'( on the outer end of the bearing sleeve and against the shaft. The bearing housingisvadapted to be lled with oil to a level above the bottom of the shaft, the stuffing boxes being depended upon, in conjunction with the cylinder or guide bearings, for preventing loss of oil around the shaft.

The oil scraper or collector 42, in the form shown in detail in Figs. 4 and 5, comprises provided inthe equalizing plates 22 if dea` box-like structure 43 having a bottom surface 44 which is transversely curved to substantially conform to the circumferential surface'45 of the thrust collar l16 (see Fig. 2) on. which it is. mounted. Said box has projections 46 which 'extend radially inward on opposite sides of the thrust collar so as to center the box thereonand it alsohas downwardly and inwardly projecting vanes or wings 56 which extend forwardly of the projections 46 and which constitute oil deiiectors as hereinafter explained. It alsohas a central lon 'tudinal partition 47 which is provided with lugs 48 and which together divide theinterior of the box into four communicating chambers. N otches or apertures 49 on opposite sides of the box form inlet openings vfor a portion of the oil collected from the rotating surface of the thrust colthe box through either lar, the oil enterin icing divided into two streams by one of the lugs 48, and being discharged through outlet" openings .f50 at the ends of Ithe box. The ends of the box are shown as extending into pockets 51 formed in inwardly projecting lugs 57 on the housing member 18, andfrom these pockets pasl.sage ways 41 lead outwardl grooves or slots 40 in the upper part of the and down-A -fffwardly to the inner ends o longitudinal The arrangement'is such that a tilting or guide bearings 13 and 14. The outer ends v of these longitudinal slots communicate with the annular grooves 32 and 33, and the lower sides of these grooves are connected with the reservoirs 11-11 by vertical passage ways 38.

IVhen the bearing is in operation the oil is carried upward from the reservoir at the bottom' of the housing on the rotating circumferential surface of the thrust collar, and the bottom edge of the collector box 42, toward which the surface is moving, acts as y a scraper and removes a large proportion of the oil therefrom, the remainder forming a `thin oil lm on which the scraper rides or floats. A part of the oil collected by the `scraper flows into the box through the opena 32, 33, and finally back into the reservoirs y shaft and they are therefore also equally 'of the direction of shaft rotation.

11-11 through the passage waysf38. The remainder of the oil that is scraped off from the revolving surface is deflected radially downward and inward by the wings 56 of the collector box 42 onto the upper side of the revolving shaft 15, and thence flows outwardly over the bearing surfaces of the thrust collar and through the spaces between the bearing shoes, thus keeping the bearing surfaces continually flooded in oil while the bearing is in operation. In order vto control or regulate the relative amount of oil that is discharged through the outlets 50 as compared with the amount that is diverted downwardly and inwardly by the side walls andA wings of the box 43, the openings or notches 49 may be made variable in width or in height; and for the purp ose of readily providing for such variation sliding gates 60 or 61 such as those shown in Figs. 6 to 9 may be suitably secured to the side walls of the box, andA ad` justed as desired. Y s

Attention is directed td the fact that even when the oil level is sufficiently high toood the bearing shoes when the parts are at rest, centrifugal' force tends to cause those portions of the shoe surfaces which are close to the shaft to run dry when the shaft and thrust collar are rotating at high speed. This tendency is fully overcome and the bearing shoes are kept constantly fiooded with oil and completely lubricated by the use of my invention.

The scraper or collector is shown as symmetrically constructed and mounted with respect to the thrust collar on which it floats or rides, and is therefore equally effective in collecting and .distributing the oil to the different portions of the bearing irrespective The grooves 4() extend longitudinally of the to the [circumferential These projecting wing or baffle walls serveeffective in securing the desired circulation of oil through the guide bearings for both clockwise and counterclockwise movements.

If desired a continuous circulation of oil through the housing may be maintained by any suitable external pumping means (not shown) connected to pipes 53 and 54 that enter the upper portion, 18, of the thrust collar housing. Inrsuch case the oil which enters through either pipe-for example the pipe 53-flows toward the center of the .housing chamber along one side of the rotating thrust collar and is deflected inwardly and downwardly toward the bearing shoes by the projecting walls and wings 46 and 56 of the scraper box. A portion of this oil also passes under the side lugs 57, which contain the feed pockets 51, to the other i side of the housing chamber z'. e., that opposite the pipe connections 53-54, and also flows over the rotating surface of-the collar'to the opposite side of the housing cham.

ber and then back to the circulating pump through the' outlet pipe 54. In order to secure a more effective circulation of the oil through all parts of the housing chamberfor both directions of shaft rotationthe housing member 18 vis shown as provided with central inwardly projecting wing walls 58-58, that are of substantially the same thickness as the thrust collar and are curved on their lower faces to conform quite closely surface thereof.

to prevent 'any transverse movement of the oil across the rotating thrust collar except at oints in proximity to the collecting and defiiecting edges of the scraper member 42, and thus cope-rate with the latter memberand with the oil circulatory means-in securing the desired positive movement of the lubricant over' and through all of the bearin surfaces.

he oil circulation through the ide bearings will still be maintained i the scraper is omitted and the oil passages 55 substituted for the passages 40, as shown in Fig. 10, but I now consider the arrangement employing the oil'scraper and deflector as preferable. c

While'the embodiment of the invention illustrated on the drawings has been described in considerable detail, it is to be understood that the invention is not limitedthereto, as the same is capable of receiving a variety of expressions some of which will readily suggest themselves to those skilled in the artl while certain features thereof are capable of use without other features thereof. While the bearing structure has been shown as duplicated on opposite sides of the thrust collar for use with a shaft on which the thrust may be in either direction, it will be understood that ifthe thrust is to be in one direction only' '.rality ofequalizin and shoes mounted on thev thrust' bearing members need be supplied on only one side of the thrust collar.V
